Sorption of Olefins in High Impact Polypropylene – Experimental Determination and Mass Transport Modeling
作者： Thomas Kröner , Michael Bartke
关键词:
摘要: Gas solubilities as well sorption rates are measured for ethylene and propylene in high impact polypropylene samples. As influenced by material properties powder morphology, non-porous polymer films analyzed the determination of effective diffusion coefficients material. These afterwards adopted modeling experiments. In that way, integral lengths powders determined. Results reveal subdomains order 250–500 μm rate determining unit mass transport. The size clusters can be described a correlation to yield; function crystallinity.
